The Well-Nut® Threaded Insert is a flanged neoprene bushing with a brass machine nut molded into one end. Tightening a conventional machine screw threaded in the brass nut causes the insert to expand, making a secure fastening. Available in a variety of rubber compounds for a full range of automotive and industrial environments.
Standard Well-Nut Threaded inserts are manufactured of neoprene with a brass insert. Other rubber compounds (such as EPDM or nitrile)) are available in most sizes upon special request. Special orders require a minimum of 25,000 pieces.
